A full blood count measures your red blood cells, white blood cells and platelets from one sample. It is the most requested private blood test in the UK and a sensible first step for tiredness, recurrent infections, bruising or a general health check. The test costs £63.75 plus the £50 phlebotomy fee, and results are usually available in 1 day.
No fasting or special preparation is needed. You can self-request the test, book online or walk in to 117a Harley Street seven days a week.
It measures the three main cell lines in blood: red cells and haemoglobin, white cells with a breakdown by type, and platelets.
No. There is no fasting or other preparation for a full blood count. Drink water as normal before your appointment.
Results are usually available in 1 day and are sent to you by email.
Low haemoglobin can point to anaemia, a raised white cell count can suggest infection or inflammation, and platelet changes can affect clotting. Any abnormal result should be reviewed with a clinician.
